One possibility is that we use the "immediate_update" attribute 
specified on the property to indicate to the auto-generated GUI that the 
property needs to be pushed immediately when the GUI changes, without 
waiting for (or affecting) "Apply".

Wonder what the rest of the team thinks about it? Are there many 
use-cases where this could be useful?

Mark, why don't you add a feature request to the bug tracker?
